摘要：

A fiber-in-tube solid-phase microextraction device based on a gold-functionalized stainlesssteel wire and tube was developed and characterized by scanning electron microscopy and energy dispersive X-ray spectroscopy. In combination with high-performance liquid chromatography, it was evaluated using six polycyclic aromatic hydrocarbons as model analytes. Important parameters including sampling rate, sample volume, organic solvent content and desorption time were investigated. Under optimized conditions, an online analysis method was established. The linearity was in the range of 0.15-50 mu g/L with correlation coefficients ranging from 0.9989 to 0.9999, and limits of detection ranged from 0.05 to 0.1 mu g/L. The method was applied to determine model analytes in mosquito-repellent incense ash and river water samples, with recoveries in the range of 85-120%.
